ApplicationV filed September My invention relates to a new and useful improvement in a. door stop and has for its object the provision door stop which will be simple in structure, economical of manufacture and highly efficient in use.

Another object of the invention isl the provision of a` door stop constructed on the principle of a hinge and adapted for folding out of operative position.

Another object of the invention is the provision of a. door stop adapted for use with doors designed to swing outwardly over unevenv` surfaces.

Another object of thel invention is ther provision of a. door stop constructed on the principle of-a toggle and adapted to engage the surface acted upon previous to swinging to or beyond center.

Another object of the invention is the provision of a door stop embodying the toggle and having means for preventingthe swinging of the stop member beyond center.

Other objects will appear hereinafter.

The invention' consists in the combination and arrangement of vparts hereinafter de-` scribed and claimed.

rIhe invention will be best understood from a reference to the accompanying draw ings which form a part of this specification and in which,

Fig. 1 is an elevational view of a door embodying the invention,

Fig.` 2 is a side elevational view of the invention applied to a door, f

Fig. y3 is a top plan view of the invention,

Fig. 4 is an elevational view of an eX- tension member used in the invention, and,

Fig. 5, is a side elevational view, with parts in section, showing the extension applied.

The invention is designed for use with swinging doors and serves as a means for preventing the undue closing of the door i after the Vsame has been opened.` It is particularly useful in connection with barns, garages, etc. although it will appear quite evident from the description that the invention is equally as well adaptable for use with all kinds of swinging doors and may be used with any door in a house -or office building when the door` is of the swinging type.

The invention comprises a body portion 2' which is made from a single blank and is provided with laterally extending anges '8 and 9, the flanges being connected to the 8, 1922.` Serial No. 586,856.

body portion by'inwardly projecting walls 18 and 19, thus causing the fianges to lie in a different Vplane than the fiat surface of the body portion. The lower end of the body portion 7 is provided with a tongue which is curledto form knuckle 10. A c0- operating member 11 is provided having a comparatively narrow tongue at each side thereof, each of which is curled to form a knuckle-12 and 13. A tongue projects" outwardly from said knuckles said tongue 14 serving as an abutment to limit the swinging movement ofthe member 11. The eXtreme end of the member 11 is turned down downwardly as at 15. The body portion v7 is adapted for attachment to a door 16 by means of bolts and screws 17. Projected through the knuckles 10, 12 and 13 is a pintle 20 so as to allow theV member 11 to swing relatively to the member 7.

When the device is inoperative the member 11 is swung to the position shown in Fig. 1. I/Vhen it is desirous to use the device tli-e member 11 is swung Vinto the position shown in 2, thus permitting the points `15 to engage the ground or flooring over which the door is swung. If it is desirous to use the device on a door inside of a building the point 15 may be capped with a rubber or cork tip 0r some other nonabrasive material.

Sometimes a door is swung over an uneven surface and to accommodate the device to this uneven surface, I have provided an eX- tension 21 which is secured to the member 11 by suitable bolts 22 and isl provided at its outer end with a` metal engaging tip 23.

It will be noted that as the door tends to swing closed the member 11 grips the surface and the tendency is to cause the member 11 to approach the centre, thus binding itself more firmly against the surface engaged.1 the principle involving the toggle joint. l

While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise form of' structure shown, but desire to avail myself ofisuch variations and modifications as come within the scope of the appended claim.

` Having thus described my invention, what I claim, as new and desire to'secure by Letters Patent is: j

A door stop of the class described comprising a channel shaped supporting member deeper at one end than at the other, and having the edges of the end Walls nnguhirly turned to prrwide ou(\\:u'cUy projectinj;- aligning 'flanges zli opposie Hides [or :uhu-lr nlent io :rr supporting surface; u knuckle 'formed on the ou'er edge of the bane of Suid supporting lnelnbexf cenrully thereof; u Hiep member cornpreng u Starnight nlun body' portion; knuckles forlncd ou .Quid 11min body portion :1t opposite Sidew` thereof 'For embracng the knuckle on Suid supporting lnenlber; n pintle projected through said knucldcs` for hingedly mounting Suid main bomby portion 011 Said supporting member; :L tongue preing into the deeper end of sun] channel between the base ol.
